Health Hazard Evaluation Report HETA 81-188-1046; Federal Correctional Institution Miami, Florida [open pdf - 2MB]
"On February 16, 1981, the National Institute for Occupational Safety and Health (NIOSH) received a health hazard evaluation request from the Superintendent of Industries, Unicor, Federal Prison Industries Incorporated, Federal Correctional Institution (FCI), Miami, Florida. The request was prompted by complaints of headaches, dizziness, nausea, and other symptoms from prison inmates who were assembling electronic components and cable connectors in the 'Industry Building'. On May 12-14, 1981, NIOSH conducted an industrial hygiene survey to determine the extent of occupational exposures to solvent vapors and solder fumes. [...] On the basis of the environmental data obtained during this investigation and due to the lack of proper ventilation in the potting section, NIOSH has determined that a potential health hazard did exist for inmates working with potting compound resins which contain residual TDI [toluene-2,4-diisocyanate]. However, the symptoms of TDI exposure are not consistent with the symptoms reported by the inmates at the Miami FCI, and no explanation can be provided at this time which would explain the liver function test abnormalities among exposed inmates."
